Penelitian ini bertujuan untuk mengidentifikasi sebaran reservoir batupasir dan menentukan zona target sumur baru pada Lapangan “X”, Formasi Talang Akar, Cekungan Sumatera Selatan, melalui analisis atribut seismik Root Mean Square (RMS) amplitudo dan peta struktur waktu. Data yang digunakan meliputi data seismik 3D, data sumur EP-15, log sumur, dan checkshot, yang diolah menggunakan perangk…
The research was conducted in Muba and its surroundings, South Sumatra. This area is included in the back arc basin which is not uncommon for geological disasters, one of which is an earthquake. The aim of this research is to identify the tectonic activity of the geological structure path associated with landform factors and to analyze the morphometric analysis of the drainage basin. The method…
Seismic tomography was applied to estimate subsurface structures West Sumatera. Based on anomalies of P- dan S-wave velocity (Vp and Vs) and Vp-Vs ratio. Earthquake data were downloaded from ISC (International Seismological Center) website from January 1, 1900 to August 31, 2021. Earthquake events with a minimum of 3 phase were selected for tomography input. Seismic velocity models and source p…
Penelitian ini bertujuan untuk mengetahui nilai Peak Ground Acceleration (PGA) di batuan dasar yang lebih spesifik untuk wilayah Kerinci dan Sungai Penuh. Analisis PGA menggunakan metode Probabilistic Seismic Hazard Analysis (PSHA) dan metode Deterministic Seismic Hazard Analysis (DSHA). Penelitian ini menggunakan data historis gempabumi dari International Seismological Center (ISC) sejak tahun…
Mentawai Achipelago is part of Sumatra Island which has two geological conditions to plate tectonic order. First, the Indo-Australian plate plunges into the Eurasian plate. Second, there is a Sumatran fault zone which is usually called Sesar Semangko or Sumatran Fault Zone (SFZ). Located between the subduction zone and the Mentawai Achipelago fault that cause earthquake activity. This study aim…
